This deck is sort of like the "Red Deck Wins" decks but is a little more combo-ish. The idea is to abuse Young Pyromancer's ability and to synergize with it. I will now provide explanations of the cards, leaving out obvious things like "Legion Loyalist has haste and the trample is good."
CREATURESFoundry Street Denizen: This guy will get big when we make tokens, which should be often.Legion Loyalist: Battalion shouldn't be difficult to pull off here and first strike is very important as most of our tokens' toughness will never be buffed so it'll help them stay alive.Ogre Battledriver: RR in cost may allow Purphoros, God of the Forge to become a creature, but it's not essential. The +2/+0 and haste for creatures entering is very good for our tokens and a late pull of a creature.Purphoros, God of the Forge: I don't expect him to become a creature too often because tokens don't have any devotion. However, when you have out Young Pyromancer and cast Molten Birth, things get silly because that's 6 damage from this guy's triggers. His 2R: Creatures get +1/+0 is nice too as you could have quite a few creatures out.Young Pyromancer: Not much to say, he makes tokens when we cast spells.
INSTANTS/SORCERIESDynacharge: for overloading for the win, may replace with Weapon Surge as it's cheaper to overload and give first strike which could be more relevant than the additional power from this.Lightning Strike: General removal and Young Pyromancer trigger, nothing special.Magma Jet: Does anything need to be said about this awesome card? Scry 2 is also useful to make sure the pieces of your semi-combo-ish deck come in order.Molten Birth: This is not bad. Let's assume the coin flip isn't present, there may be another card that makes tokens for cheap in our colors. However, there IS the coin flip. Not that this debate matters though as Krenko's Command is gone. (This is being written assuming it'll be read post-rotation). That's 50% chance you get this card back. And when that means at least 2 (more with Young Pyromancer) 3/1 haste guys (Ogre Battledriver) that deal 2 on entry (Purphoros, God of the Forge), heck yes, you want this card.
PLANESWALKERS/SPECIAL LANDSMutavault: This deck is based on the Red Deck Wins style and at the end of the day isn't venturing too far out of the familiar waters, we still have only one color and a low-ish curve. This card is still good in this deck.Chandra, Pyromaster: The +1 on her is just awesome. In my local metagame I believe people still underrate her somewhat. Her 0 ability is also mroe useful than you think, it's one of those abilities that you never see how good it is until you play it out. Do it before you drop your land/play a card if you need a draw, or if you have enough mana to cast anything in the deck and don't need any of her other abilities-- This way you always get something you can play. Her +1 may usually be better because it is a damage and it does stop a blocker. Her ultimate is sort of a pipe dream but casting 3 Molten Births could be funny for reasons mentioned earlier.
SIDEBOARDMindsparker: No real reason other than it helps the race for damage versus finding answers (card draw) against blue/white decks. There may be better options.Burning Earth: I've already (this is being written pre rotation) seen less 3 color decks, and I bet this will continue to hold true more post rotation when this deck becomes legal. So, this is in the sideboard for now, it may come out, I don't see it going main though, but like always, we'll see.Skullcrack: Sphinx for 4? No, instead you take 3.Wild Ricochet: Probably not good at all, but this seems good against counter spell users and other decks with burn. (This can counter a counter, choose to not choose new targets for their counter then with your copy target their counter, just in case you didn't realize this. You probably did though.)Mizzium Mortars: Side this in when they've got bigger stuff that Lightning Strike just can't take care of. Or if you feel like trolling the troll, side in against Firedrinker Satyr. (I think his face looks like the troll face kind of. I wouldn't actually recomend siding this in against him though.)
